PFA patch which will add functionality to allow user to comment/uncomment code in query editor.
RM#2456
This is cool, but I'm not sure it's right as-is:
* I prefer SQL style commenting, e.g.
-- This is a comment
Should we make that a config option if CodeMirror can do it? Or a different hotkey?
* You've added it as an option to the Clear XXX dropdown, which really isn't the right place in my opinion. Should we add a new drop down for this, and include some/all of the other Editing options on there? E.g. tab/shift-tab.
* I think the docs should say Ctrl+Shift+/ rather than Shift+Ctrl+/, and be ordered in the table to reflect that. It seems more natural to me.
